The Intel Core Ultra 5 245KF is the objective winner of this comparison, securing victories in twelve out of fourteen measured specifications. While the Intel Core i5-10600K maintains a slight 8% advantage in MSRP, the newer processor dominates in architectural capacity. The most impactful technical improvement is found in the L2 cache, where the Intel Core Ultra 5 245KF offers a massive 1633% increase over the Intel Core i5-10600K, providing a significant leap in memory-related performance.

Users prioritizing the lowest initial cost should select the Intel Core i5-10600K, as it remains the more affordable option based on MSRP. Conversely, those building a modern system who require the substantial technical benefits provided by the vastly superior L2 cache should choose the Intel Core Ultra 5 245KF. By opting for the latter, buyers gain a component that outperforms its predecessor across nearly every measured specification, making it the clear choice for users seeking maximum hardware capability.
